Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on Technical scheme in the present invention, those of ordinary skill in the art obtained under the premise of creative work is not made it is all its His embodiment, belongs to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention provides a kind of air centrifugation expansion compression all-in-one technical scheme:A kind of air centrifugation Expansion compression all-in-one, including frame 11, it is characterised in that:The upper end of frame 11 is provided with driving support seat 6, and driving support seat 6 Interior to be provided with main shaft 5 by bearing assembly 10, the left side of main shaft 5 is provided with compressor impeller 8, and the left side of driving support seat 6 leads to The fast quick-mounting folding larynx hoop 7 of overcompression machine spiral case is provided with compressor scroll 9, and the right side of main shaft 5 is provided with expanding machine impeller 1, transmission Larynx hoop 4 is rolled over by expanding machine spiral case fast quick-mounting expanding machine spiral case 2, expanding machine impeller 1 and compressor leaf are installed in the right side of bearing 6 Wheel 8 is sealed using bearing seal 12 with bearing assembly 10, and expansion guide ring 3 is provided with expanding machine spiral case 2.
Be provided with into protruding shaft in expanding machine impeller 1 and compressor impeller 8, and main shaft 5 be provided at both ends with into protruding shaft The inward recess of matching, into being filled and being assembled using alloy piece interference between protruding shaft and inward recess, wherein sheet metal can be used Aluminium alloy leaf, aluminium alloy leaf is freezed at low temperature makes its volume diminish, and is subsequently placed into inward recess and into the crack of protruding shaft, rises Can clamping after temperature.
Bearing assembly 10 includes bearing, and being provided at both ends with for bearing is combined in complex disk spring and circlip, uses The structure results in the rigidity and stability higher than cylindrical compression spring, and can provide more preferable vibration absorbing performance, adopts The compactedness that the product is ensure that to the occupancy of axial space is reduced with the bearing assembly.
Operation principle:It is first that abbreviation compressed air under the compressed air of -20 DEG C of food-grades is expanded when the device works The suction inlet of machine spiral case 2 is radially into expansion guide ring 3, and the uniform edge of the expanded guide ring 3 of compressed air expands guide ring 3 Water conservancy diversion annular groove curve blows to expanding machine impeller 1, because snail tongue and the expansion guide ring 3 of expanding machine spiral case 2 constitute single channel, Compressed air can only enter expanding machine impeller 1 by setting runner.So as to drive expanding machine impeller 1 to rotate, main shaft 5, bearing assembly 10 and bearing seal 12 play a part of support expanding machine impeller 1, if the rotating speed of compressed air-driven expanding machine impeller 1 is N1, it is P1 to realize acting, and it is n1 and work(P1 to be installed on the compressor impeller 8 of the opposite side of main shaft 5 according to the rotating speed of expanding machine impeller 1 The parameters such as the diameter of compressor impeller 8, compression ratio are determined as the design parameter of input compressor impeller 8, so that it is determined that whole The structural parameters of centrifugal compressor part.The kinetic energy produced by compressor part and the acting of expanding machine part is coaxially directly inputted Form mechanical energy is converted into the kinetic energy and potential energy of compressed gas, because without intermediate conversion links, the device will possess high Energy conversion efficiency.The axial force that the axial force that the rotation of expanding machine impeller 1 simultaneously is produced is produced with compressor impeller 8 can be mutually Offset, so that bearing assembly 10 is to bear based on radial load, so as to improve the whole service life of bearing assembly 10.
When the initial pressure of compressed air is 2.5 bar, compressed air enters swollen in the expanded radial flow path of machine spiral case 2 During swollen machine part, gradually increase because its cross section of fluid channel accumulates the compressed gas speed that gradually tails off.Compressed during by expanding guide ring 3 Gas is uniform tangentially radially into expanding machine impeller 1 with expanding in lead ring, and normal direction promotes impeller rotate counterclockwise.Immediately Expanded conduit is axially exported, and realizes that compressed gas is externally done work.From thermodynamic (al) principle:Intermolecular interior kinetic energy size is anti- Reflect temperature height T, intermolecular interior potential energy size reflection specific volume V, interior energy=interior kinetic energy+interior potential energy, u=(T, V).Expansion is externally done Work(consume interior energy, interior potential energy increase consumption gas in itself interior kinetic energy as compensation gas temperature drop.- 20 DEG C are determined through model machine Compressed air, the expanded external actings of the bar of pressure 2.5 are promoted, and compressed air pressure is measured at expansion diffusion conduit outlet - 80 DEG C are reached for 1.5bar dielectric gas temperature.The rotating speed of main shaft is up to 38000rpm.And the expanding machine impeller 1 used for Half-opened impeller is conducive to improving the critical speed of impeller, and expanding machine impeller 1 is then by the overall milling impeller intensity of high strength alumin ium alloy High, transmission efficiency.
The air centrifugation expansion compression all-in-one that the present invention is provided reduces unnecessary intermediate energy conversion links, and Using the axial load on the compressor part at main shaft two ends and expanding machine balance of plant main shaft 5, dress is not only increased The service life put and being capable of preferably stationarity and energy conversion efficiency, using the teaching of the invention it is possible to provide a kind of speed of mainshaft reaches 38000rpm New conversion equipment, dielectric gas temperature reaches that dielectric gas temperature reaches -80 DEG C, is fully able to meet the cold of seafood on the market Freeze cold-storage needs, with very high practical value.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
